ULTRASONIC BRONCHOFIBERVIDEOSCOPE BF-UC180F
• Before transnasal insertion, apply the appropriate
pretreatment and lubrication to the patient to enlarge the
nasal cavity. Otherwise, operator and/or patient injury can
result or the endoscope could become lodged and be difficult
to withdraw. Otherwise, the treatment will have no effect. The
effects of the pretreatment agent and lubricant will decrease
the longer the procedure lasts. Apply the pretreatment agent
or lubricant as required during the procedure
when withdrawal seems to be difficult.
• The temperature of the distal end of the endoscope may
exceed 41C (106F) and reach 50C (122F) due to intense
endoscopic illumination. Surface temperatures over 41C
(106F) may cause mucosal burns. Always maintain a
suitable distance necessary for adequate viewing while using
the minimum level of illumination for the minimum amount of
time. Do not use close stationary viewing or leave the distal
end of the endoscope close to the mucous membrane for a
long time without necessity.
• Whenever possible, do not leave the endoscope illuminated
before and/or after an examination. Continued illumination
will cause the distal end of the endoscope to become hot and
could cause operator and/or patient burns.
• Turn the video system center ON to operate the light source's
automatic brightness function. When the video system center
is OFF, it cannot operate the light source's automatic
brightness function, and the light intensity is set to the
maximum level. In this case, the distal end of the endoscope
can become hot and could cause operator and/or patient
burns.
• If any of the following phenomena occur during an
examination, immediately stop the examination and withdraw
the endoscope from the patient as described in Section 10.2,
"Withdrawal of the endoscope with an irregulality".
 If any irregulality is suspected with the functionality of the
endoscope.
 If the endoscopic image on the monitor disappears or
freezes unexpectedly.
 If the angulation control mechanism is not functioning
properly.
Continued use of the endoscope under these conditions
could result in patient injury.
